This process can enable efficient PET recycling in a single step with pure polymer being recovered from the solvent. Chemical recycling methods also offer a valuable future pathway to deliver virgin grade rPP. Overall, innovations in recycling food grade PET and PP are paving the way for a more sustainable future in food packaging and may be applicable to the recycling of other polymer materials commonly used in the packaging industry. PET has a higher recycling rate, with more than three quarters of used PET drinks bottles being collected and recycled in the UK, according to Which? data. However, innovations in labelling and sorting rPP can ensure that food grade PP can be separated and used again. Another method of recycling PET involves making use of organic solvents.
